甲状腺结节内钙化与甲状腺癌的关系研究

目的 探讨超声探测到的甲状腺结节内钙化与甲状腺癌的关系.方法 收集本院5年间行甲状腺手术患者4186例,对比甲状腺结节术前彩色超声检查与术后病理诊断.结果 甲状腺癌患者甲状腺结节内钙化,微小钙化和非微小钙化的发生率明显高于良性疾病中的发生率(P＜0.05).微小钙化对于预测甲状腺癌更有意义(P＜0.01),它在≥45岁和＜45岁组问比例分别为2.4%和16.8%,差异有统计学意义(P＜0.05);钙化在不同性别问差异无统计学意义(P＞0.05);伴钙化的恶性结节在单发与多发组间比例为70.7%和49.1%,差异有统计学意义(P＜0.05).结论 超声探测到微小钙化病灶对诊断甲状腺癌的特异性高,特别是对乳头状甲状腺癌.微小钙化对诊断微小乳头状癌有重要临床意义.

Calcified thyroid nodules and thyroid carcinoma

Objective To investigate the calcification of thyroid nodules detected by ultrasound and its relation with thyroid carcinoma.Methods Four thousand one hundred and eighty-six cases of thyroid disease were surgically treated during a period of five years.Retrospective analysis was made to compare preoperative color Doppler ultrasound and postoperative pathology.Results The incidence of calcification,non-microcalcification,and microcalcification were significantly higher in thyroid carcinoma than that in benign diseases(P＜0.05).For predicting thyroid cancer,microcalcification was more significant than non-microcalcification(P＜0.01).There was a significant difierence in the microcalcification between the different age groups(2.4%for patients of 45 and older,16.8%for patients younger than 45;P＜0.05):There was no difference in the calcification between male and female groups(P＞0.05);There was a significant difierence in malignant calcified nodules between difierent nodule groups(70.7%for patients of solitat'y.49.1%for patients of muhiple:P＜0.05).Conclusion Microcalcifications in the thyroid is related to thyroid cancer.especially to micro-papillary carcinoma.
